TILE-MACHINE.

SPECIFICATION forming part of Letters Patent NO. 519,773, dated May 15,1 894:.

Application filed April 22,1893- Sezial No. 471,487. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. PRIDE, a citizen of the UnitedStates,residing at S pring field, in the county of Sangamon and State ofIllinois, have invented a certain new and useful Improvement inTile-Machines, of which the following is such a full, clear, and exactdescription as will enable those skilled in the art to which it pertainsto make and use my said invention.

My improvementis intended to be attached to any of the force-feed tilemachines now in common use.

I do not lay any claim to the tile machine itself, and hence illustrateonly so much of the machine as is necessary to illustrate the connectionof my improvement therewith.

The purpose of my invention is to provide means whereby any suitableconfiguration or ornamentation may be given to the tiles as they emergefrom the machine.

Reference is hereby made to the accompanying drawings in which- Figure1- is a perspective view of my improvement connected with the tilemachine. Fig. 2-- is an enlarged detached view of one of the housings inwhich the impression roll works. Fig. 3- is a detached view of analternative construction of the molds adapted to be used in the bed.Fig. 4- isa detached View showing an alternative form of the impressionroll, also showing an alternative form of mold adapted to be used in thebed. Fig. 5-- is a representation of some of the various designs whichmay be impressed on the tiles by means of my improvement.

Similar letters indicate similar parts in all the views.

The pug mill A is of ordinary construction and may be provided with anysuitable means for kneading the clay and forcing it through the mouth aof the mill. The bed B may be connected in any suitable manner with thepug mill, and this bed is supported on suitable legs I). The bottom ofthe bed may be flat, or may be provided with channels 0, or may berounded, ridged or furrowed in any suitable manner to give any desiredform to the under side of the tile. The bottom molding surface may beintegral with the bed. I prefer however to use molds O detachablyconnected with the bed in any suitable man- It is obvious that greatvariety in the form of the bottom of the tiles maybe obtained by varyingthe forms of the channels in the bed.

The impression roll D is journaledin boxes d, and theseboxes slide inhousings E, which are bolted or otherwise suitably secured to the bed B,being guided by lugs (1 moving in vertical slots e in the sides of thehousings. Within the housings and on top of the sliding boxes are coiledsprings F, and above the springs are followers G, which also movevertically and are guided by lugs on the followers, said lugs moving inthe slots 6. In the top of the housings are screws H which may be turneddown on top of the followers, thereby compressing the springs F andgiving elasticity and any desired pressure to the impression roll.

In the drawings I have shown only one impression roll, but in practicetwo or more rolls may be used, placed parallel to each other, or placedend to end, without departing from my invention.

On the periphery of the roll D are wrought the forms and designs 01which it is desired to give or to impress upon the face of the tiles.These designs may be either in relief or in intaglio, and a greatvariety of designs may be used. In Fig. 5 I have indicated a few ofthem, but I do not confine myself to the designs shown. A single designmay occupy the entire surface of the roll or two or more designs may beplaced side by side or end to end on a single roll. It is obvious alsothat the roll may be ridged and furro wed as shown in Fig. 4, or mayhave any other suitable form, thus adapting the machine to produce greatvariety in the form as well as the ornamentation of the upper surface ofthe tiles.

The impression roll D is made solid and heavy so that the. weight of theroll may be the bearings of the roll to rise in the housings when thereis undue pressure on the roll thus permitting the roll to pass over hardsubstances in the clay without injury to the roll.

The operation of my machine is as follows:

The clay after being properly ground and kneaded in the pug mill A isforced out through the mouth a, in a yielding and pliable mass .into themold O in the bed B, and is pushed along in the mold and under therollD. The pressure of the movingclay actuates the roll and the pressureof the roll forces the under side of the clay into the .channels 0 inthe molds, and at the same time the roll impresses on the uppersurface'of the clay the form or the design which is wrought in theperiphery-of the roll, and this operation continues as long as the claycontinues'to issue from the mouth of the pug mill.

The slab-of clay formed andimpressed, as

above describedmay bereceived onany suitfor propelling said slab of clayin such mannor as to rotate said roller by the pressure of said movingslab of clay acting against the periphery of said roll, as set forth andfor the purpose stated.

2. In a tile machine, the combination of the bed adapted to be connectedwith the mouth of the pug mill, the longitudinal mold detachablyconnected with the bed, the housings on the bed and the roll journaledand vertically movable in said housings, as set forth and for thepurpose stated.-

3. In a tile machine, the combination of the 7 bed attachable to themouth of the pug mill, the longitudinal. molds detachably secured insaid bed, the housings on the bed, the boxesslidin g in said'housings,the impression roll journaled ,insaid boxes, the springs acting againstsaid boxes, the followers in the housingsabove the springs and thescrews operating said followers-asset forth and for the purpose stated.

4. In a tile machine, the @bed attachable to the pug mill and adapted.to impress on one side of the tile the counterpart of the conformationof thesurfaceof the bed, incombination with the vertically adjustableand WILLIAM H. PRIDE.
